I paid R7900 more than 4 months for a car with a disc that is epixired

I took a vehicle on the 23 of January 2025 with a disc that was going to expire on the 31st of January2025, the company promised to send me another disc before expiry date of that one, even asked for my delivery address. I called them several times complaining, I phoned the company telling them that I want to cancel, they said I must return the car. I tried returning the car, along the way I was stopped by police because of the expired disc I apologized and told them that the car does not belong to me. I rent it. The advised me to go back. Of which I did. I contacted NFC again telling them my story I asked for driver they said I will pay R3000 if I need a driver. That time it is not my fault but theirs and I have already paid for more than 4 months while the car disc is expired. I even told them that I cant use the car the way I wanted to due to the disc. But they said I must pay R3000 for car to be collected. I really don't like the way this company operates.
